This Dataverse entry contains all the .R scripts and input/output data associated with Mleczko, Matthew. "The Cumulative Exposure to Exclusionary Zoning in Impoverished Neighborhoods." Demography. Forthcoming.

To replicate the results, the user can run all of the code in sequential order (each .R script is named explicitly to indicate its place in the pipeline). Each .R script also has a detailed header indicating the input and output data files. The user can also replicate the final results (as opposed to replicating the entire workflow) by simply running the 202_ regression .R scripts and/or the 203_ and 204_ results .R scripts. 

Note that the user will need to specify paths and file names to run these .R scripts. These are indicated in the .R scripts with placeholders such as # USER DEFINED FILE PATH HERE # or # USER DEFINED PATH AND FILE NAME HERE # 

Several of these .R scripts contain code that is borrowed or lightly adapted from Mleczko, M., & Desmond, M. (2023). Using natural language processing to construct a National Zoning and Land Use Database. Urban Studies, 60(13), 2564–2584. https://doi.org/10.1177/00420980231156352 (see https://github.com/mtmleczko/nzlud)

Several of these .R scripts also contain code that was generated with assistance from Microsoft Copilot or Google Gemini
